The object of this invention is to provide a double-pointed pin fastening device, especially one designed for use of automobile trimmers to pin or attachseat and other covers to the fabric on the inside of auto'mo biles.

Fastening devices of the type represented in this invention are usually provided with a cap made as a metal shell and attached to the pin in a variety of ways. In the casev of singlepointed pins, the head of the pin has been made usually of ring form, and the cap made with a flanged rim in which the ring is mounted. In thecase of a double-pointed pin, having a cap, it is expensive to make the capengaging end or head of the pin in the form of a ring, and it is diflicult and expensive to connect the double-pointed pin head and the cap and to prevent relative turning of the pin within the cap. The limbs of the double- 7 pointed pins tend to approach one another in y the act of setting.

cap at opposite points,

Our invention consists of a double pointed pin, having a looped head bent over substantially parallel with the limbs of the pin and spaced apart from the limbs so as to form a cap-engaging head, which is engaged by the instead of circularly, as in-the case of a ring.

The invention also consists of i a doublepointed pin having a retaining prong integral with the cap and adapted to automatically en gage the fabric on which the pin is used and from which it may be disengaged as desired.

The invention also consists of a doublepointed pin, having means for separating the elevation, and Fig. 3 is a rearelevation, il-

. lustrating one embodiment of the invention. 4 is a rear elevation of the shell-like cap. Fig. 5 is a section on line 55 of Fig. 3. Fig. 6 is a'rear elevation, and Fig. 7 a front elevation of the double-pointed pin detached.

Fig. 8 is a rear elevation, and Fig.9 is a sectlon on line 9-9 of Fig.8, illustrating the automatically operating retaining prong.

Fig.10isa rear elevation, and Fig. 11 a s'ec= 01011 on line 111 l-of Fig. 10, illustrating the separating feature. "Fig.12 isa rear elelimbs pointed, and the looped end bent over and humped at the top so as to fit within the shell. which forms the cap. l'designates the limbs, 2 their pointed ends, 3 the looped head having the humped portion 4 which engages the upper portion of the cap and the bend 5 which engages the lower portion of the cap, an d 6 is the cap having the flanged rim 7 which confines the head of thepin within the cap in a rigid. fixed or stationary manner.

The looped and humped endor head of the p n differs from, any other to us known, in that itis bent back upon the limbs and parallel or 111 alignment with said limbs, the portions 8 thereof being straight, instead of cirvation, illustrating the'use of both prong and'lugQ f i The double-pointed pin isconveniently i straight portions '8 shaped to engage the cap within its flange 7 and thence slanting outwardly, as at 10, and merging with the limbs and carrying said limbs outside of the cap, so that said limbs may be engaged with the article to which the pin is applied as a fastener.

The limbs engage the notches 11 in the lower edge of the flange 7 so as to be held spaced apart and aid in preventing relative movement of the cap and pin.

The pin with its described head is capable of economical manufacture and ready assembly with the cap, with the tendency of relative movement of the cap and pin reduced if not entirely eliminated.

The cap may be provided with an inverted V shaped prong 12 projecting upwardly and outwardly at an angle from the lower portion of the flange and between the limbs of the pin, and of a width at its base about equal to the distance between said-limbs so as to hold the limbs apart. Thisprongis fixed and adapted to engage automatically the fabric Li I on which the fastenerfis usedto prevent the dent l c p' Qt the fa t ner; nd a er such engagement the fabric is held in place. through the resilient tendenci e'sof the limbsof "Inprller t"disengage the prong Ham-the fabrie a'sharp tool, such as a thin knife blade, may be inserted between the 7 fabric and the bottom of thecap, to thereby force the limbs of the pin away fromthe fixed prong and lessen the friction set up vby the resilient limbs of the pin, as"we11. as, forcing the fabric ahead of the leadingedge over the point of the prong. When this tool reaches the head of the prong-it covers it, as it were,

' and prevents a further tendencytowards lock;

As shown in Fig..12,both prong 12, and lug 13 may be used ina pin fastenen, a
